Object-based Vegetation Type Mapping from an Orthorectified Multispectral IKONOS Image using Ancillary Information
Vegetation Types Multispectral IKONOS Image Segmentation Quality
2015/11/16
Traditional pixel-based image classification approaches have some limitations with the use of very high spatial resolution imagery.
In recent years, object-based image analysis (OBIA) approaches has...
摘要 以五分地沟试验区为例，利用IKONOS卫星遥感图像，结合DEM，对地形复杂的黄土丘陵地区制作植被图，并进行三维显示，直观地表达了研究区域植被的空间分布。使用景观指数，分析了植被空间格局的特点。结果表明，试验区整体格局较破碎，但斑块稳定性较好，分维数为1.25。人工植被占主导地位，人工乔木林和农田成为基质，天然植被、水体等类型以小斑块的形式镶嵌其中。经过综合治理，当前的植被结构和空间布局能有利...
IKONOS影像在城市绿地提取中的应用
2007/8/24
本文以南京城市为例，重点讨论了基于IKONOS影像的城市绿地信息分级分类提取方法，通过将IKONOS多光谱数据合成，根据各类地物的不同光谱特征，采取相应的方法提取出各层信息。在此过程中，仔细分析地物间在IKONOS 4个波段中的光谱差异，非线性增强阴影区绿地的NDVI值，利用光谱差异分层提取、剔除信息，最后把各分级绿地信息合并得到整体绿地分布图。分级分类法充分考虑各类目标的...
